Bug#615491: xserver-xorg-core: does not fill correctly for complex boundaries



Package: xserver-xorg-core
Version: 2:1.7.7-11
Severity: normal


The PLplot development team have just implemented a demanding 2D fill
rendering test for the X stack where we modify our standard example 27
(see http://plplot.sourceforge.net/examples.php?demo=27) to change
from drawing the boundary line of "spirographic" (e.g., hypotrochoid
and epitrochoid) curves to filling those curves.  The boundaries
of the 9 test curves are illustrated in the first attachment.

The fills of those test curves (implemented using XFillPolygon with a
Complex shape and 20000 points in the polygon describing the boundary)
have rendering errors.  

If the fill is done with the EvenOddRule filling rule (set using
XSetFillRule) the rendering errors are severe. The first through 3rd
test cases show blank results (not illustrated) and the 4th test case
(second attachment) and remaining more complex fill cases (not
illustrated) show severe rendering errors with many fills missing and
some areas filled that should not be.  

If the fill is done with the WindingRule filling rule, the fill
rendering errors are much less severe than in the case of the
EvenOddRule filling rule. The first (attached), second (not
illustrated) , and 3rd (not illustrated) test cases look fine, but the
fourth (attached) and remaining (not illustrated) test cases have
minor rendering errors (areas filled which should not be on the
right-hand side of the figure so the total result is asymmetric rather
than symmetric as it should be for the symmetric hypotrochoid and
epitrochoid boundary curves of the fill.

Because most applications and libraries (including the PLplot one)
have great success with X filling with a small (3 or 4) number of
points in the boundary for the normal default EvenOddRule filling
rule, I tried the experiment of reducing the number of points from
20000 to 200, but that made no qualitative difference to the severely
bad fill rendering for the EvenOddRule filling rule.

PLplot has a great many device drivers other than the xwin one used to
produce these results.  For many of them (for example, Qt-based and
pango/cairo-based devices), I tried both the winding number fill rule
and the odd-even fill rule, and I got results consistent with those
described above where I was using a device that depended on X
directly.  That result makes sense since these libraries ultimately
end up calling X to display these filled results for complex
boundaries using either of the two filling rules.  So ultimately, all
of these different bad fill results for complex boundaries must be
caused by fill issues in the X stack.

I am not sure which package in the X stack is responsible for filling
so please move this bug report to the appropriate package if
xserver-xorg-core is not responsible for filling. Also, I am virtually
positive this is an upstream issue.  I am therefore completely willing
to propagate this bug report elsewhere (if the Debian X strike force
doesn't want to do that themselves), but I need guidance on which
component of the X stack is responsible for filling before I do such
propagation.

Finally, I am not sure exactly how to attach screenshots to Debian
bugs using reportbug so I may have to do that later if it does
not work with this initial report.
